It could easily be a conflict with anti-virus sw. I use MS Security Essentials and it pops up a window every now and then saying SPP is possible malware.

On my 6 core HP Z800 SPP 5.4.0 would crash every time I saved files. SPP 5.4.1 was a bugfix version for this known problem with computers with over "9 threads or more" according to Sigma. The software is a little buggy but Sigma do seem to be trying to iron out the problems.

Try what carsten said or try to go back to the last good version that worked for you.

I've found highlights to be decently recoverable, not quite as good as my D800 but definitely decent. I've only taken about 300 shots on my DP2M so I don't have much experience, so keep that in mind with respect to my response.

Any workaround for long exposure speeds...i want to be able to use NDs, and 30 sec won't cut it perhaps....
